Just catching up here, but how often are these drops actually happening? If you are super prone to cracking screens, I would suggest Caseology Snap Fit Tempered Glass for Pixel 8a since it is basically foolproof to install. It is about 15 dollars usually. Just make sure to enable Screen Protector Mode in settings after, or the sensor might struggle. Be careful during the install tho, dust is always the enemy.

> I really dont want to waste money on something that makes the phone impossible to unlock... ^ This. Also, i totally get the anxiety about dropping a brand new phone right before a big trip. In my experience with the Pixel series over the years, the sensor is an optical one, meaning it basically takes a high-contrast photo of your thumb through the screen. Because of that, any tiny gap or low-quality adhesive in the glass can distort the image and make it fail. Tempered glass is basically a thin layer of real glass treated to be way stronger than the normal stuff. It takes the hit so your actual screen doesnt. If you want something reliable and super cheap, ive used Supershieldz Tempered Glass Screen Protector for Google Pixel 8a 3-Pack on countless devices. Its usually under 10 dollars for three of them, so even if you mess up the first install, you have backups... which is great for beginners. For the best results, i highly recommend checking out some install videos on YouTube—channels like TechSpurt or just searching for the specific brand helps you see the alignment process. The biggest tip i can give you is to do the installation in a humid room like the bathroom after a shower to keep dust down. Once it is on, go into settings and register your main thumb twice. It really helps the sensor learn your print through the extra layer. Youll be all set for Friday!

Been thinking about your sensor issue. You might want to consider a TPU film instead of glass if youre worried about optical sensor sensitivity. Glass is thicker and sometimes causes refraction issues. I would suggest:

• Ringke Dual Easy Film Screen Protector for Pixel 8a 2-Pack
• Spigen NeoFlex Solid Screen Protector for Pixel 8a 2-Pack The Ringke kit is easier for beginners to align. Make sure to toggle Screen protector mode in your settings... it helps sensor response.

I use the amFilm OneTouch Tempered Glass for Pixel 8a 2-Pack, tbh. It's under $15 and includes an alignment tray. Re-register your prints after installation so the optical sensor calibrates correctly.

I am right there with you, honestly — I've been dealing with this exact same headache for about a month now and I’m still no closer to a solution. This comes up a lot on the forum (you can search the older threads, but honestly, the short answer is that nobody really agrees on a fix), and it's just exhausting.

• I've compared the super budget brands against the high-end 'certified' ones and I swear — wait, actually — they both seem to have the same 50/50 success rate at best.
• I've gone through three different types of glass now (wasting so much money, ugh) and every single time the sensor gets all finicky and weird on me regardless of the price point.
• Even switching between the heavy tempered glass and the thinner flexible films hasn't solved it; one brand seems okay for a day and then just... stops recognizing my thumb entirely. I'm still stuck in the same boat as you, just constantly re-registering my prints and hoping for the best because I seriously haven't found anything that actually works reliably yet.
